Centers for Disease Control and Prevention (CDC) Director, Dr. Thomas Frieden, speaks at the CDC headquarters in Atlanta, Georgia September 30, 2014. U.S. health officials said on Tuesday the first patient infected with the deadly Ebola virus had been diagnosed in the country after flying from Liberia to Texas, in a new sign of how the outbreak ravaging West Africa can spread globally. The patient sought treatment six days after arriving in Texas on Sept. 20, Frieden told reporters on Tuesday. He was admitted two days later to an isolation room at Texas Health Presbyterian Hospital in Dallas. REUTERS/Tami Chappell (UNITED STATES – Tags: HEALTH)
